title: Observability for AG2 with Opik
description: Start here to integrate Opik into your AG2-based genai application for end-to-end LLM observability, unit testing, and optimization.
---

[AG2](https://ag2.ai/) is an open-source programming framework for building AI agents and facilitating cooperation among multiple agents to solve tasks.

AG2's primary advantage is its multi-agent conversation patterns and autonomous workflows, making it ideal for complex tasks that require collaboration between specialized agents with different roles and capabilities.

## Getting started

To use the AG2 integration with Opik, you will need to have the following
packages installed:

```bash
pip install -U "ag2[openai]" opik opentelemetry-sdk opentelemetry-instrumentation-openai opentelemetry-instrumentation-threading opentelemetry-exporter-otlp
```

In addition, you will need to set the following environment variables to
configure the OpenTelemetry integration:

<Tabs>
    <Tab value="Opik Cloud" title="Opik Cloud">
        If you are using Opik Cloud, you will need to set the following
        environment variables:
            
        ```bash wordWrap
        export OTEL_EXPORTER_OTLP_ENDPOINT=https://www.comet.com/opik/api/v1/private/otel
        export OTEL_EXPORTER_OTLP_HEADERS='Authorization=<your-api-key>,Comet-Workspace=default'
        ```

        <Tip>
            To log the traces to a specific project, you can add the
            `projectName` parameter to the `OTEL_EXPORTER_OTLP_HEADERS`
            environment variable:

            ```bash wordWrap
            export OTEL_EXPORTER_OTLP_HEADERS='Authorization=<your-api-key>,Comet-Workspace=default,projectName=<your-project-name>'
            ```

            You can also update the `Comet-Workspace` parameter to a different
            value if you would like to log the data to a different workspace.
        </Tip>
    </Tab>
    <Tab value="Enterprise deployment" title="Enterprise deployment">
        If you are using an Enterprise deployment of Opik, you will need to set the following
        environment variables:

        ```bash wordWrap
        export OTEL_EXPORTER_OTLP_ENDPOINT=https://<comet-deployment-url>/opik/api/v1/private/otel
        export OTEL_EXPORTER_OTLP_HEADERS='Authorization=<your-api-key>,Comet-Workspace=default'
        ```

        <Tip>
            To log the traces to a specific project, you can add the
            `projectName` parameter to the `OTEL_EXPORTER_OTLP_HEADERS`
            environment variable:

            ```bash wordWrap
            export OTEL_EXPORTER_OTLP_HEADERS='Authorization=<your-api-key>,Comet-Workspace=default,projectName=<your-project-name>'
            ```

            You can also update the `Comet-Workspace` parameter to a different
            value if you would like to log the data to a different workspace.
        </Tip>
    </Tab>
    <Tab value="Self-hosted instance" title="Self-hosted instance">

    If you are self-hosting Opik, you will need to set the following environment
    variables:

    ```bash
    export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:5173/api/v1/private/otel
    ```

    <Tip>
        To log the traces to a specific project, you can add the `projectName`
        parameter to the `OTEL_EXPORTER_OTLP_HEADERS` environment variable:

        ```bash
        export OTEL_EXPORTER_OTLP_HEADERS='projectName=<your-project-name>'
        ```

## Using Opik with AG2

The example below shows how to use the AG2 integration with Opik:

```python
## First we will configure the OpenTelemetry
from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.resources import Resource
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.instrumentation.openai import OpenAIInstrumentor
from opentelemetry.instrumentation.threading import ThreadingInstrumentor


def setup_telemetry():
    """Configure OpenTelemetry with HTTP exporter"""
    # Create a resource with service name and other metadata
    resource = Resource.create(
        {
            "service.name": "ag2-demo",
            "service.version": "1.0.0",
            "deployment.environment": "development",
        }
    )

    # Create TracerProvider with the resource
    provider = TracerProvider(resource=resource)

    # Create BatchSpanProcessor with OTLPSpanExporter
    processor = BatchSpanProcessor(OTLPSpanExporter())
    provider.add_span_processor(processor)

    # Set the TracerProvider
    trace.set_tracer_provider(provider)

    tracer = trace.get_tracer(__name__)

    # Instrument OpenAI calls
    OpenAIInstrumentor().instrument(tracer_provider=provider)

    # AG2 calls OpenAI in background threads, propagate the context so all spans ends up in the same trace
    ThreadingInstrumentor().instrument()

    return tracer, provider


# 1. Import our agent class
from autogen import ConversableAgent, LLMConfig

# 2. Define our LLM configuration for OpenAI's GPT-4o mini
#    uses the OPENAI_API_KEY environment variable
llm_config = LLMConfig(api_type="openai", model="gpt-4o-mini")

# 3. Create our LLM agent within the parent span context
with llm_config:
    my_agent = ConversableAgent(
        name="helpful_agent",
        system_message="You are a poetic AI assistant, respond in rhyme.",
    )


def main(message):
    response = my_agent.run(message=message, max_turns=2, user_input=True)

    # 5. Iterate through the chat automatically with console output
    response.process()

    # 6. Print the chat
    print(response.messages)

    return response.messages


if __name__ == "__main__":
    tracer, provider = setup_telemetry()

    # 4. Run the agent with a prompt
    with tracer.start_as_current_span(my_agent.name) as agent_span:
        message = "In one sentence, what's the big deal about AI?"

        agent_span.set_attribute("input", message)  # Manually log the question

        response = main(message)

        # Manually log the response
        agent_span.set_attribute("output", response)

    # Force flush all spans to ensure they are exported
    provider = trace.get_tracer_provider()
    provider.force_flush()
```
